Our preselltfinvention relates to the art'of bottling accessories andmore particularly to a sediment collectingcap which is intended for useonbeyerage bottles of the effervescent type.

"The general purpose of our present invention is similar to that showninour co-pending application, Serial No. 286,625, filed June 19, 1928.fMany sediment collecting devices have been created but most of themhave the inherent fault of being difiicult to clean. Others have smallvalve members, upon Whose action little; dependence can be placed. Inour presentcase we believe We have overcome the outstandingdisadvantages indicated and d at the same time are ableto produce abottlecap which clamps securely to the bottle, which can be made cheaplyand be used over and over again without fear of any L damage.

Therefore, 1 7 v v object of our present inventionis to provide a simplebottle cap which will collect and retain'sediment precipitated bybeverages. c W Afurtherobjectis toproduce a sediment collecting cap thatmay be easilycleaned;

Other and more specific objects will be apparent from the followingdescription taken in connection with the accompanying drawings, wherein00 Figure 1 is an elevation partly in section, showing our sedimentcollecting cap secured to'abeverage bottle. V

shape of chamber 12'is a matter of preference. "It has been founddesirableto have the. generalshape cylindrical, although for ease inmanufactureit is usually more convenient ,to have it slightly coned withthe small end at the closed end of chamber 12. This is a manufacturingexpediency and gives draft for theeasy removal of cores which are usedThe end wall 24 of chamber 12 should preferably beflat and normalto theaxisiof the bottle when the cap is in place. I This is desirable inorder thatthe bottles maybe easily stoodupside down, it being necessaryto so place the bottles in order that the sediment will filterdownwardly and come to rest withfin, chamber 12.

. Normally disposed, partially within the bottle B and-partiallywithinthe cavity 12 is a valve member 30. This consists of'a stem- 32upon which .is mounted a valve 34. It is so believed apparent that valve34 might be 3 formed as a part of stem 32. However, owing to thevariation in bottles it is often more desirable to have this valveformed sothatit snugly encircles stem 32 and in this manner should be upas high as will permit of a free how of the sediment past it, orrather,between it andthe bottle. This of course ,is

with the aim of providing the maximum available storage space in chamber12 for the sediment. It has further been founddesirable to form thelower end of stem '32 as a iball 36 This member might be. dispensedwith. a I

However, referring to Figure 1, itis believed apparent that if no ball36' were provided the stem 32 would lie in close contact with the innersurface of the bottle neck and seals the same.

would thus form a natural lodging place for any sediment flowingdownwardly. The ball shape of course could be easily changed to aconical shape with the point uppermost, as viewed in Figures 1 and 4.

Method of operation In operating our device it isusual to fill bottle Bwith the desired fluid up to the usual level. Valve member 30 is thenplaced in position as indicated in Figure 3. The cap proper i is thengrasped in the hand and the mouth of the bottle entered into the conedportion 16. By applying downward pressure and twisting the cap slightly,it will-be found to go on very easily. It has been found, however, thatit willTengage moreeasily and smoothly if thecapsare soaked in water fora few minutes, or at least are thoroughly wet. The water in this caseacts as an excellent lubricant, preventing any frictional engagementbetween the glass and the rubber cap. The beverage bottle with the capthus attached is then inverted as indicated in Figure 4. 7 Valve member30, due toits own weight, dropsdownwardly until the end of stem 32engages the bottom wall 24 of the cap. This spaces the valve 34 at theproper distance both from the bottle itself and from the bottom of thecap. The bottle is allowed to stand in this manner until all thesediment has been precipitated. Ordinarily, little,if any, will lodge onthe sloping surface l0 of the valve. In some instances, however, thismay occur. This condition may be remedied, however, by inclining thebottle about as indicated in. Figure 1 and. slowly revolving it for aturn or two. This is normally sufficient to dislodge any sediment whichmay have come to rest onsurface or. eveuon the upper surface of ball 36.The beverage should then be replaced to the positi'on shown'in Figure 4:until it is certain that all sediment has been precipitated. The bottlemay then be inverted to the position indicated in Figure 3. The valvemember 30 will drop downwardly until valve 34 engages the upper surfaceof the bottle mouth and Now normally the bottle will not beinverteduntil just before its content is .to be used, but itis possibleto invert the same at anytime after the sediment has all beenprecipitated.

To. open the bottle,.bo'dy 10 is graspedby the hand and with a slightlytwisting effort the cap is bent over to one side until it is entirelyremoved. -'lhis,operation is normally best performed over some vessel,as it is very desirable to keep the bottle substantially upright and itusually entails, of course, the spilling of the contents of chamber 12.The

valve member 30, however, has been found to adequately protect the openmouth of the bottle, even. though it iirsoine cases maybe removed fromthe bottle by being engaged by groove 14., as has been indicated inFigure 2.

The foregoing description and the accompanying drawings are believed toclearly disclose a preferred embodiment of our invention but it will beunderstood that this disclosure is merely illustrative and that suchchanges in the invention'may be made as are fairly within the scope andspirit of the following claims:

A sediment collecting cap consisting of a body portion formed ofresilient material and adapted to provide a sediment collecting chamber;an annular groove, disposed near the open end of said chamber, adaptedto ena bottle head; a valve assembly. having a coned valve adapted toengage the mouth of a bottle and a valve stem both disposed within saidchamber and adapted to space said valve away from the end of saidchamber. V

2.
